| 22 ;;; Synched up with: FSF 19.30. (font-lock.el) | |
| 23 | |
| 24 ;;; Commentary: | |
| 25 | |
| 26 ;; The reason for the existence of this file is so that modes can | |
| 27 ;; call `font-lock-set-defaults' without worrying about whether | |
| 28 ;; font-lock is loaded. We don't autoload this from font-lock.el | |
| 29 ;; because loading font-lock.el automatically turns font-lock on. | |
| 30 | |
| 31 ;;; Code: | |
| 32 | |
| 33 (defun font-lock-set-defaults (&optional explicit-defaults) | |
| 34 "Set fontification defaults appropriately for this mode. | |
| 35 Sets `font-lock-keywords', `font-lock-keywords-only', `font-lock-syntax-table', | |
| 36 `font-lock-beginning-of-syntax-function' and | |
| 37 `font-lock-keywords-case-fold-search'. | |
| 38 | |
| 39 If `font-lock-defaults' is currently set, it is used. Otherwise, the | |
| 40 symbol naming the major mode is examined for a `font-lock-defaults' | |
| 41 property. If that is not present, but a variable `foo-mode-font-lock-keywords' | |
| 42 is, the value of that variable is used as the default for | |
| 43 `font-lock-keywords'. Various other backward-compatible behaviors also | |
| 44 exist -- if you're curious, look at the source. | |
| 45 | |
| 46 The value of `font-lock-maximum-decoration' is used to determine which | |
| 47 set of keywords applies, if more than one exists. | |
| 48 | |
| 49 This will also put the buffer into Font Lock mode if any keywords exist | |
| 50 and if auto-fontification is called for, as determined by | |
| 51 `font-lock-auto-fontify', `font-lock-mode-enable-list', and | |
| 52 `font-lock-mode-disable-list'. | |
| 53 | |
| 54 Calling this function multiple times in the same buffer is safe -- this | |
| 55 function keeps track of whether it has already been called in this | |
| 56 buffer, and does nothing if so. This allows for multiple ways of getting | |
| 57 Font Lock properly initialized in a buffer, to deal with existing major | |
| 58 modes that do not call this function. (For example, Font Lock adds this | |
| 59 function to `find-file-hooks'.) | |
| 60 | |
| 61 Major modes that have any font-lock defaults specified should call this | |
| 62 function during their initialization process, after they have set | |
| 63 the variable `major-mode'. | |
| 64 | |
| 65 If EXPLICIT-DEFAULTS is t, this function will not check whether it | |
| 66 has already been run in this buffer, and will always do the full | |
| 67 computation. | |
| 68 | |
| 69 If EXPLICIT-DEFAULTS is not nil and not t, it should be something | |
| 70 that is allowable as a value for `font-lock-defaults' and will be | |
| 71 used to initialize the Font Lock variables." | |
